Metafile Viewer is a free software that is compatible with all versions of Windows, allowing the user to load and view both 16-bit and 32-bit metafiles. It supports vector graphics, raster images, and text with fonts, and enables the user to view multiple files tiled or cascaded.

This tool is an excellent choice for professionals due to its outstanding performance, which allows for unlimited zooming for large and detailed drawings. It even allows you to print to Windows printers.
As an operating system level format, WMF and EMF can be challenging to preview. However, with the free Windows Metafile Viewer, you can open them in a Windows application. It's worth noting that this viewer is a sample application that the developers created to demonstrate the power of their SDK for Windows.
Suppose you are a developer or systems integrator that needs to work with Metafiles. In that case, you should check out their Developer Center, where you can find an API and command-line tools for converting WMF and EMF to PDF and other vector and image formats. If you have a specific project, you can contact them, and they will likely be able to offer assistance.
